Subject: [9front] boot/efi: support framebuffer with 64-bit base address
Date: Thu, 18 Feb 2021 08:58:35 +0000 [thread overview]
Message-ID: <C0D9A13E6FF1D15A9EAEE323C406407A@arrow.hsd1.ca.comcast.net> (raw)
My thinkpad t14 (amd) uses a framebuffer at 0x460000000, which got
truncated to 0x60000000 in *bootscreen.
